The Tenebraex Objective flip cover protects the lens of your scope from dust and bad weather conditions. The flip up cover could be attached in any position, for that it provides ambidextrous performance for every shooter and scope mounting situation.
These are tough, durable, protect the lens well, and so far have not flown apart on my 50 BMG like certain other brands. I think they will hold up a good, long time. No regrets!
Have used Butler Creeks for years, and may never buy another!! These Tenebraex covers fit securely, are easy to adjust the flip angle - work great...
I managed to achieve perfect bore-to-scope distance with my Nightforce SHV 4.5-14x56 on Sig SSG 3000 with millimeters to spare. Had a modified Butler Creek Blizzard cover. Had to carve out the bottom to get it over the scope and not touch the barrel, but the cap did not close properly.
This high quality screw in adaptor and cover combo fits basically flush with your scope and now I have the perfect protection and fit for a perfectly set up rifle. Durability and quality of build looks excellent so far, but only time will tell.
Thanks also for great service fast shipping from Mile High Shooting!!
